土地测量员没法看清前面是什么，因为他的整片视野被车夫宽大而笨拙的背挡住了。

The surveyor could not see what was in front as his whole field of vision on that side was covered by the broad clumsy back of the driver.

将树枝拖到前面，为垃圾分拣提供便利也不是什么好玩儿的事。

Hauling the branches to the front for garbage pick up was no fun either.

The order complexity here, if I actually write it would be-- sorry, order n times m, and if m was equal to n, that would be order n squared, and this is quadratic.

如果m等于n的话,也就是n的平方，这是一个平方复杂度的问题，这是和前面不同类型的，好，我在做什么呢？
